  The wireless base station 400 is a device that relays wireless communication between the system controller 200 and the wireless terminal 500. In the present embodiment, the UWB (Ultra Wide Band) method is assumed for wireless communication performed between the system controller 200 and the wireless terminal 500 via the wireless base station 400. This is because when the process of detecting the position of the radio base station 400 and the position of the radio terminal 500 using the UWB method is performed, the position accuracy is as high as about ± 15 cm, which is sufficient for the position detection. In the base station position measurement process described later, the positions of a plurality of radio base stations 400 are measured.

  In addition, the terminal control unit 510 transmits a start request that prompts the system controller 200 to start measurement (detection) of the position of the own wireless terminal 500 and an end request that prompts the end of measurement. In addition, as information for measuring the position of the wireless terminal 500, the terminal control unit 510 causes a timer or a clock to function to determine the radio wave propagation time and the radio wave intensity between the plurality of radio base stations 400 and the radio terminals 500. Measure and send the information to the system controller 200.

  The terminal storage unit 520 is configured by a predetermined storage device such as a ROM (Read Only Memory) or a flash memory, for example, and in addition to an operation program (application) executed by the terminal control unit 510, data necessary for execution of each process Or data acquired or generated by execution of each process. The processing by the wireless terminal 500 is realized by the terminal control unit 510 executing the operation program stored in the terminal storage unit 520.

  The terminal input unit 530 includes various keys, buttons, or a touch panel for receiving instructions from the user, and inputs various instructions and data to the terminal control unit 510. The terminal input unit 530 receives a request for starting and a request for ending the process of measuring (detecting) the position of the wireless terminal 500 from the user. These requests are transmitted to the system controller 200 via the terminal communication unit 550. In addition, the terminal input unit 530 receives a request for correcting the trajectory and layout information.

  The terminal display unit 540 includes, for example, a dot matrix type LCD or organic EL panel and a driver circuit, and displays an arbitrary image. The terminal display unit 540 displays the position information of the wireless terminal 500 and the layout information of the room in which the device 100 is installed, which is transmitted from the system controller 200.

  The terminal communication unit 550 includes an interface for performing communication and the like, and mediates wireless communication performed between the system controller 200 and the wireless terminal 500 via the wireless base station 400 according to a predetermined protocol. .

  Next, the operation of the system controller 200 shown in FIGS. 1 and 2 will be described. The process executed by the system controller 200 includes a position measurement process for measuring the position where the radio base station 400 is installed, a layout setting process for setting a space area (indoor layout) where a plurality of devices 100 are installed, and a device There are roughly three types of device setting processes for setting 100 installation positions. First, the position measurement process will be described with reference to FIGS.

  After the plurality of radio base stations 400 are installed, the system controller 200 prompts the user to perform a position measurement operation, and when receiving some input operation from the user, the system controller 200 determines the position of the radio base station 400. The position measurement process to be measured is started.

  First, the control unit 210 prompts the user to set a radio base station 401 that is a base point for measuring the position of the radio base station 400. Then, the control unit 210 controls the input unit 230 or controls the communication unit 250 to receive information from the wireless terminal 500, accepts the wireless base station 401 as a base point, and receives the wireless base station 401. Is set as a base point (step S101). As illustrated in FIG. 5, the control unit 210 sets the received coordinates of the base point in the radio base station 401 as the intersection coordinates (0, 0) between the X axis and the Y axis.

  Next, the control unit 210 controls the input unit 230 and the like, receives a radio base station 402 corresponding to the base radio base station 401, which is different from the base radio base station 401, and The station 402 is set as a corresponding point (step S102). When the distance between the radio base station 401 and the radio base station 402 corresponding to the radio base station 401 is Dab, the control unit 210 sets the coordinates of the corresponding point in the radio base station 402 to be on the X axis, The coordinates of the corresponding point are set as (Dab, 0).

  Here, regarding the setting of the radio base station 402, the radio base station 403 that measures the position is either one of the straight lines with respect to the straight line (axis) connecting the radio base station 401 and the radio base station 402. In addition, it is preferable to set the radio base station 402. This is because the calculation processing burden of the position measurement process can be reduced. For this reason, typically, the radio base station 400 located on the corner or wall side of the room where the radio base station 400 is installed is set as the radio base station 401 serving as the base point or the radio base station 402 corresponding to the base point. To do.

  Next, the control unit 210 controls the base station position measurement unit 211 to perform another wireless communication based on the position of the wireless base station 401 serving as the base point and the position of the wireless base station 402 corresponding to the base point. The position of the base station 403 is measured (step S103). As shown in FIG. 5, first, the control unit 210 draws a circle having a radius R1 centered on the base point (0, 0) and a circle having a radius R2 centered on the corresponding point (Dab, 0). Next, the control unit 210 obtains an intersection where two circles intersect, and draws a triangle connecting the intersection, the base point, and the corresponding point. And the control part 210 calculates | requires the coordinate (X1, Y1) of an intersection from the triangle which the length (Dab, R1, R2) of 3 sides was decided. The coordinates (X1, Y1) of this intersection are the position of the radio base station 402.

  Next, the control unit 210 determines whether there is a radio base station 403 whose position has not been measured (step S104).

  When there is a radio base station 403 whose position has not been measured (step S104; Yes), the control unit 210 measures the position of the radio base station 403 whose position has not been measured (step S103). The control unit 210 obtains the coordinates (X2, Y2), (X3, Y3), (X4, Y4) of the intersections in the same manner as the coordinates (X1, Y1) of the intersections. The position of the station 403 is determined. By repeating the processes of steps S103 to S104, the positions of all the radio base stations 403 are measured.

  On the other hand, when there is no radio base station 403 whose position is not measured (step S104; No), the control unit 210 determines that there is no radio base station 403 whose position is to be measured, and ends this process.

  Through the above processing, by setting the base station 401 and the base station 402 corresponding to the base point, the positions of all the base stations 400 installed in the device setting support system 1 are measured. can do.

  Next, layout setting processing for setting an indoor layout in which a plurality of devices 100 are installed will be described with reference to FIGS.

  The system controller 200 starts this process after the position measurement process for measuring the position of the radio base station 400 is completed.

  First, the control unit 210 determines whether or not there is a request from the wireless terminal 500 to start position measurement of the wireless terminal 500 (step S201).

  When there is no start request (step S201; No), after waiting for a predetermined time, the control unit 210 determines again whether there is a request from the wireless terminal 500 to start position measurement of the wireless terminal 500 (step S201). S201).

  When there is a start request (step S201; Yes), the control unit 210 measures the position of the wireless terminal 500 based on the radio wave intensity and the radio wave propagation time between the plurality of radio base stations 400 and the radio terminal 500 ( Step S202). Note that the process of detecting the position of the wireless terminal 500 includes, for example, a method using that the radio wave intensity of wireless communication is proportional to the nth power of the distance, a method using the radio wave propagation time, a trilateration method, The method described in 318553 gazette etc. is used.

  Next, the control unit 210 records the position of the wireless terminal 500 measured in step S202 (step S203).

  Next, the control unit 210 determines whether or not there is a request from the wireless terminal 500 to end the position measurement of the wireless terminal 500 (step S204).

  When there is no termination request (step S204; No), the control unit 210 continues to measure the position of the wireless terminal 500 (step S202).

  Here, when performing the processing from step S202 to step S204, as shown in FIG. 7, the user moves the wireless terminal 500 along the outer periphery 600 of the room where the wireless base station 400 is installed. When the user who owns the wireless terminal 500 moves, the wireless terminal 500 moves as the user moves. The process of measuring the position of the wireless terminal 500 in step S202 is performed every predetermined time period (for example, one second period). When the position of the moving wireless terminal 500 is measured every predetermined time period, a trajectory 601 in which the wireless terminal 500 has moved can be obtained from the plurality of measured positions. A route from the start point to the end point of the movement of the wireless terminal 400 becomes a locus 601, and a spatial area (layout) is indicated by an area surrounded by the locus 601.

  When there is an end request (step S204; Yes), the control unit 210 controls the trajectory generation unit 212 and based on the plurality of positions of the wireless terminal 500 measured in steps S202 to S204. A trajectory 601 that has moved is generated (step S205). Since the locus 601 is obtained by the user moving along the outer periphery 600 in the room, the locus 601 and the outer periphery 600 of the space region have a shape that substantially matches. For this reason, a locus 601 whose shape substantially coincides with the outer periphery 600 can be used as a spatial region (layout) indicating the indoor boundary position and size.

  Next, the control unit 210 controls the area specifying unit 213 to specify (generate) the layout of the room in which the plurality of devices 100 are installed based on the generated locus 601 and display a screen showing the layout. (Step S206). Since the shape of the trajectory 601 and the shape of the outer periphery 600 of the room in which the device 100 is installed substantially match, the control unit 210 generates a room layout that matches the shape of the trajectory 601, so that the plurality of devices 100 are arranged. Specify the space area (layout) of the installed room. Further, the control unit 210 transmits the locus 601 and the layout to the wireless terminal 500 via the communication unit 250, and the wireless terminal 500 displays the transmitted information. Thereby, the user can visually recognize the locus 601 and the indoor layout.

  Next, the control unit 210 controls the input unit 230, or controls the communication unit 250 to receive information from the wireless terminal 500, and whether there is a correction request from the user to correct the layout. Is determined (step S207).

  When there is a layout correction request (step S207; Yes), the control unit 210 controls the input unit 230 and receives a correction instruction from the user (step S208). As shown in FIG. 8, when the shape of the locus 601 does not match the shape of the outer periphery 600 and a certain radio base station 403 is outside the locus 601, the user wants to modify the locus 601 (trajectory icon). By operating (for example, dragging and dropping), the locus 601 can be corrected as appropriate.

  Then, when the correction of the layout is finished, this process is finished. If there is no layout correction request (step S207; No), it is determined that the layout has been set, and the process ends.

  Through the above processing, the indoor layout in which the plurality of devices 100 are installed can be automatically set based on the locus 601 in which the wireless terminal 500 has moved.

  Next, device setting processing for setting the installation position of the device 100 will be described with reference to FIGS. 9 and 10.

  The system controller 200 starts this process after the layout setting process is completed.

  First, the control unit 210 extracts an arbitrary device 100 from among a plurality of devices 100 included in the device installation support system 1 (step S301). For example, the control unit 210 extracts the devices 100 in the order of the ID numbers included in the devices 100.

  Next, the control unit 210 requests that the wireless terminal 500 be moved to the installation position where the extracted device 100 is installed (step S302). The control unit 210 extracts the device 101 (step S301), and requests the user to move the wireless terminal 500 to the installation position where the device 101 is installed (step S302). The wireless terminal 500 is moved to the installation position where is installed. The control unit 210 controls the communication unit 250 to transmit information to the wireless terminal 500, and the user who owns the wireless terminal 500 reaches the installation position where the device 101 is installed while visually recognizing the information received by the wireless terminal 500. The wireless terminal 500 is moved.

  Next, the control unit 210 detects (measures) the position of the wireless terminal 500 (step S303). Note that the method of measuring (detecting) the position of the wireless terminal 500 is the same processing as in step S202 of FIG.

  Next, the control unit 210 determines the measured position of the wireless terminal 500 as the installation position where the device 100 is installed (step S304). In FIG. 10, the user moves the wireless terminal 500 to the installation position where the device 101 is installed, and the control unit 210 detects the position of the wireless terminal 500 at the installation position. For this reason, the position where the wireless terminal 500 is detected matches the installation position where the device 101 is installed. Therefore, the control unit 210 determines that the position where the wireless terminal 500 is detected is the same as the installation position of the device 100, assuming that the position where the wireless terminal 500 is detected is the same as the installation position where the device 101 is installed. Thereby, the self-identification information (ID) of the device 100 can be associated with the installation position where the device 100 is installed.

  Next, the control unit 210 determines whether there is another device 100 to be extracted (step S305).

  When there is another device 100 (step S305; Yes), the control unit 210 extracts the device 100 that has not been extracted from the plurality of devices 100 included in the device installation support system 1 (step S301). When the device 101 has already been extracted, the control unit 210 extracts any of the devices 102 to 105 other than the device 101. And the installation position of all the apparatuses 100 is determined by repeating the process of step S301-S305.

  On the other hand, when there is no other device 100 (step S305; No), the control unit 210 controls the setting unit 214 to output an image representing the installation position of the device 100, assuming that all the devices 100 have been extracted. (Step S306). As illustrated in FIG. 10, the control unit 210 displays an indoor layout (an image of the outer periphery 600) in which the device 100 (devices 101 to 105) is installed, and further displays an image of the device 100 whose installation position is determined ( Images of the devices 101 to 105). The control unit 210 transmits image information to the wireless terminal 500 via the communication unit 250, and the wireless terminal 500 displays the transmitted image information. Thereby, the user can confirm the installation position of each apparatus 100 by visually recognizing the image indicating the installation position where the apparatus 100 is installed.

  Next, the control unit 210 controls the input unit 230 or controls the communication unit 250 to receive information from the wireless terminal 500 to correct the installation position of the device 100 from the user. It is determined whether or not there is (step S307).

  When there is a request for correction of the installation position (step S307; Yes), the control unit 210 controls the input unit 230 and the like and receives a correction instruction from the user (step S308). As illustrated in FIG. 11, when the position of the wireless terminal 500 and the installation position of the device 104 do not match, the user operates (for example, drags and drops) the device 104 (device icon) to be corrected. The installation position of the device 104 can be corrected as appropriate.

  Then, when the correction of the installation position of the device 100 is completed, this process is terminated. Further, when there is no request for correction of the installation position (step S307; No), it is assumed that the setting of the installation position of the device 100 has been completed, and this processing ends.

  With the above processing, the position where the wireless terminal 500 is detected becomes the installation position of the device 100, so that the installation position of the device 100 can be automatically set. Further, the self-identification information (ID) of the device 100 can be associated with the installation position of the device 100.

  As described above, the indoor layout in which the device 100 is installed can be automatically set based on the trajectory 601 that the wireless terminal 500 has moved. Then, the installation position of the device 100 in which the self-identification information (ID) of the device 100 and the installation position of the device 100 are associated can be displayed on the layout. For this reason, the load for installing the device 100 can be reduced, and human errors during installation can also be reduced.

(Embodiment 2)
In the device installation support system 1 according to the first embodiment, the case where the radio base station 400 exists independently has been described. In the present embodiment, a case where the device 100 includes (also serves as) the wireless base station 400 will be described. In addition, about the structure and operation | movement similar to the apparatus installation assistance system 1 which concerns on Embodiment 1, description is abbreviate | omitted suitably.

  FIG. 12 is a diagram showing a device installation support system 2 according to Embodiment 2 of the present invention. As shown in the figure, the device installation support system 2 includes a plurality of devices 100 including a wireless base station 400, a system controller 200, a dedicated communication line 300, and a wireless terminal 500. Similarly to the first embodiment, the system controller 200 and the wireless terminal 500 are connected via the wireless base station 400 so that wireless communication is possible.

  The storage unit 220 stores in advance the correspondence between the self-identification information (ID) of the radio base station 400 and the self-identification information (ID) of the device 100 including the radio base station 400. Thereby, when the radio base station 400 is identified, the device 100 including the radio base station 40 can be identified.

  In the present embodiment, since the device 100 includes the radio base station 400, the measured position of the radio base station 400 is the installation position where the device 100 is installed. For this reason, the system controller 200 can determine the installation position of the apparatus 100, without implementing the apparatus installation process shown in FIG. Next, processing for setting (measuring) the installation position of the device 100 according to the present embodiment will be described with reference to FIG.

  Here, the processing of steps S101 to S104 is the same operation as that of the first embodiment, and thus description thereof is omitted. In the first embodiment, when there is no radio base station 400 whose position has not been measured (step S104; No), the present process is terminated, but in the present embodiment, the installation position of the device 100 is not terminated. Is displayed (step S306). This is because the installation position of the radio base station 400 and the installation position of the device 100 match, so that the position of the radio base station 400 measured in step S103 can be determined as the installation position of the device 100. Note that the processing in steps S306 to S308 is the same as that in the first embodiment, and thus the description thereof is omitted.

  Through the above processing, the cost for installing the radio base station 400 can be reduced. Further, by detecting the position of the radio base station 400, the installation position of the device 10 can be detected. Further, by detecting the installation position of the device 100, the self-identification information (ID) of the device 100 can be associated with the installation position of the device 100. For this reason, in this embodiment, the burden which installs the wireless base station 400 can be reduced. Moreover, the process which measures the installation position of the apparatus 100 can be simplified.

  The installation position of the radio base station 400 is arbitrary. In the second embodiment, the device 100 includes the radio base station 400, but it is not necessary that all the devices 100 include the radio base station 400, and there may be an independent radio base station 400.

  The wireless communication performed between the system controller 200 and the wireless terminal 500 via the wireless base station 400 is any wireless communication that can measure (detect) the position of the wireless base station 400 and the position of the wireless terminal 500. Also good.

  Further, the radio base station 400 and the radio terminal 500 can also have a GPS (Global Positioning System) function. The system controller 200 can also measure the positions of the radio base station 400 and the radio terminal 500 using the GPS function.

  In the position measurement process, when the number of the radio base stations 400 is two or less, or when the radio base stations 400 are installed on a straight line, the installation position of the radio base station 400 can be detected by the trilateration method. Can not. In such a case, a new radio base station 400 can be installed so that the radio base stations 400 do not line up on one straight line. Thereby, the position of the radio base station 400 can be measured (detected) by the position measurement process described above.

  The trajectory generation unit 212 can also generate the trajectory 601 based on the position of the wireless terminal 500 that has moved an arbitrary place in the room. In FIG. 14, the wireless terminal 500 is moving in a place other than the outer periphery 600 in the room. The trajectory generation unit 212 measures (detects) the position where the wireless terminal 500 has moved, and generates a trajectory 601 based on the plurality of measured positions. Then, the area specifying unit 213 can specify an arbitrary area based on the locus 601 generated by the locus generating unit 212. In FIG. 15, three regions are identified from the three trajectories 601, and a boundary 602 that partitions the room is identified. Since the user can move the wireless terminal 500 to an arbitrary place, the trajectory generating unit 212 can generate an arbitrary trajectory based on the position where the wireless terminal 500 has moved. For this reason, the user can also divide one room into a plurality of regions desired by the user by moving the wireless terminal 500.

  The processing performed by the system controller 200 can also be performed by the wireless terminal 500.

The wireless terminal 500 can also include various sensors such as a temperature sensor, a humidity sensor, an illuminance sensor, and a CO ₂ sensor.
